Recent studies show that livestock grazing can significantly enhance habitats for native bees, particularly ground-nesting species.
About 70% of the 4,000 bee species in the United States build their nests underground, requiring small patches of bare ground for nesting. When rangelands are covered with litter, these bees struggle to find suitable places to lay eggs and raise their young.
Research funded by the USDA-Conservation Effects Assessment Project (CEAP) in Montana has revealed that pastures with grazing livestock have double the number of ground-nesting bees compared to ungrazed areas. This highlights the vital role that livestock play not only in agriculture but also in supporting pollinator populations.
Pollinators are essential for global food production, contributing an estimated $550 billion annually to food supplies. They also support diverse wildlife by providing food sources and promoting healthy soils.
Unfortunately, pollinator populations face numerous threats, including habitat loss, pesticides, climate change, and disease. Sustainable practices, such as livestock grazing, can help restore and maintain their habitats.
Researchers from Montana State University found that grazed pastures had nearly twice as much bare ground and significantly less leaf litter, creating optimal nesting conditions for bees.
Ben Lehfeldt, a sheep and cattle rancher, noted that properly managed grazing improves soil health and boosts insect populations, benefiting both agriculture and the ecosystem.
The findings emphasize the importance of preserving rangelands for livestock grazing to support not only agricultural productivity but also pollinator health.
As urban development encroaches on these lands, it is crucial to recognize the interconnectedness of livestock agriculture and biodiversity conservation.
